Interface FloatEntry
- All Superinterfaces:
AnnotationConstantValueEntry, ConstantValueEntry, LoadableConstantEntry, PoolEntry
public sealed interface FloatEntry extends AnnotationConstantValueEntry, ConstantValueEntry
Models a
CONSTANT_Float_info structure, or a float constant, in the constant pool of a class file. The use of a FloatEntry is modeled by a float. Conversions are through ConstantPoolBuilder.floatEntry(float) and floatValue(). In the conversions, all NaN values of the float may or may not be collapsed into a single "canonical" NaN value.
